WINDOW-SASH coNsT'RuorroN c.

Application filed August 11, 1928. Serial No. 299,041:

This invention relates to improvements in window sashes and more particularly to a window sash of the sliding type.

The prime aim of this invention is to obviate the necessity which at present compels window washers to expose themselves exteriorly of a window in order to properly clean the same, thus subjecting themselves to considerable danger and frequently because of the imminence of this danger the outer side of the sash is not thoroughly cleaned.

The prime object of this invention therefore is to provide a side construction for windows wherein the pane may be reversed within the sash frame to permit the cleaning of both sides thereof without endangering the person so working. i

Another important object of the invention is to provide a window sash construction of the above nature capable of being easily adjusted to reversed position and being of such simple construction as to allow the manufacture thereof at a cost only slightly above the cost of the present type of sash.

Still another object resides in the means employed for connecting the reversible pane to the sash frame whereby the pane may be swung completely inward of the sash frame 7 and reversed to a position convenient to the person cleaning the same.

After reading the following specification and claims, other important objects and advantages of the invention will become apparent.

In the drawing:

Figure 1 is an inside elevation of a window construction equipped with the present improved sash structure, 7

Figure 2 is an edge elevation of the window frame partly broken away and disclosing the inner frame of the lower sash disposed part- 1y away from the sash frame, while the dotted lines disclose the position the inner frame will assume when in complete reversed position,

Figure 3 is a side elevation of the improved sash construction,

Figure 4 is a horizontal sectional view through the window frame and one of the improved sashes taken substantially on line H of Figure 1, and looking in a downward direction, and

Figure 5 is a vertical sectional view through a fragmentary portion of the invention dlSf closing the means employed for securing the inner frameto the outer frame of each'sash construction. 1 I Y l I 7 Referring to the drawings wherein like numerals designate like parts, a window frame A is provided in the usual manner with the guide strips B between which the sashes are slidable, v i The present invention relates to improvements in slidable sashes and are engageable with the window framein'the usual manner. As the upper and lower sashes of a window construction such as is disclosed in Figure 1 of the drawings are identical, the description of one will suffice for both. '70

'i The sash consists of an outer frame 1 provided with an inwardly disposed'fiange 2 arranged continuously within the frame. The inner vertical edge portions of the outer frame lare formed with elongated channels 33. j The portion of the flange 2 at the top of the outer frame 1 has a plate4 secured to its outer side and is formed with a threaded opening therein in registry with an opening through the flange 2. v 1 The sash also includes an inner frame 5 'within' which a "transparent pane 6 is mounted. Obviously, this pane neednot necessarily be of a single sheet, as the ,inner frame 5 may be allotted into numerous divisions devised to retain a plurality of panes if desired.

An elongated arm 7 is pivotally secured at i one of its ends to the upper end portion of each channel 83 of the outer frame 1. Each vertical edge of the inner frame 5 is formed throughout a major portion of its length with an undercut groove. A plate 1.8 is formedf throughout its intermediate longitudinal portion with an undercut channehan'd this intermediate portion is disposed within the undercut groove of the inner frame edge in the manner designated by numeral 9.

The opposite ends of the arms ,7 are equipped with laterally disposed protuberances 10 each having an enlarged head 11 engaged Within the undercut channel of the plate 8.

Obviously, by moving this latter end portion of each of the arms 7 to the lowermost portion of the plate 8, the inner frame may be disposed within the outer) frame in the manner shown in Figure 1. p

A threaded bolt 12 provided with a wing head 13 is engageable through anopening in the upper portion of the inner 'frame' 5 while its threaded end portion may be fed into the threaded opening of the plate l'whereby" to secure the inner frame within the outer frame.

By unscrewing the bolt 12, the inner frame 5 may be pulled outwardly ofvthe outer frame to a position as shown in Figure2. By effect,- ing a substantial horizontal pullfion :the upper end ofthe inner frame, the outer ends of the arms 7 "will be disposed toward the opposite end of the slotted plateJ8. y

In this manner the inner frame will assume a reversed position whereby the pane may certainly be easily cleaned. 1

Obviously, certain changes in the specific shape, size or materials may be resorted to without departing from the spirit or scope of the appended claims.

.Having. described the invention, whatI claim as new is: v

1. In a sash structure comprising an. outer slide frame,an inner frame engageable Within the outer frame, said inner frame being formed with a-pair of its opposite' edges grooved, and a pair of armspivoted atlone of their ends to the outer frame and having their opposite ends slid'ably engaged within the grooved. edges of the arms whereby' 'the same inner frame may be moved. outwardly j of the outer frame and swung-to a reversed position.

2. In a sash structure comprising an outer frame, an inner frame for supporting a trans,- Iparent pane, and means for reversing said inner frame within the outer frame, said means consisting of a link. pivotall'y connected to the outer frameanddsl'idablycon.- nected to theinner frame. V

In testimony whereof I afiix my signature.
